Bony sesamoiditis in a patient with plantar forefoot pain. Short axis PD (a) and T2-weighted fat-saturated (b) images reveal a mild asymmetric pattern of bone marrow oedema confined to the medial hallucal sesamoid. Note lack of oedema in the lateral hallucal sesamoid, first metatarsal head and surrounding soft tissues. Oblique sesamoid radiograph (c) shows no discernible abnormality. These results suggest bony sesamoiditis or stress reaction
